Enterprises and governmental agencies process personal data of their clients for, e.g., personalised services and to get access to services as a proxy for them. By the Directives 95/46/EC and 2002/58/EC, the EC has defined data protection and security principles in order to regulate the processing of personal data. User centric identity management empowers clients in controlling the disclosure of their personal data to organisations. For information chains as found in multi-staged processes identity management may lead to a big-brother phenomenon. Clients have to trust organisations that they process personal data according to their privacy and security policies, along the chain of participating parties. This workshop aims at these challenges and discusses first approaches for privacy enhancing technologies (PET) and their use in current and future business and governmental process models. The workshop itself will be jointly organised by the IST FP6 projects FIDIS and PRIME.
